HAROLD S. MADDOCK, OF TRENTON, NEW JERSEY, ASSIG-NOB TO THOMAS MADDOCKS SONS COMPANY, OF TRENTON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

WATER-CLOSET.

Application filed July 17, 1915.

, To all whom it may concern: 1

Be it known that I, HAROLD S. MADDooK, a citizen of the United States, and a resident of Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Tater-Closets, of which the following is a specification.

My invention relates to the construction of water closets of porcelain or other earthy material particularly of the siphon jet type.

The present invention is particularly useful when embodied in water closets for installing in prisons, jails and similar institutions where the users of the same are inclined to be destructive or careless.

The object of the invention is to provide a construction in which joints in the closet bowl are avoided and in which clogging of the same by throwing towels or other material into the same cannot be effected.

Water closets for use by prisoners in prisons and jails are usually disposed in a niche and are provided with a slab forming the seat and it has been the practice to employ a loose or detachable slab rendering the making of a joint between the slab and bowl This always leads to trouble as it is very diflicult to make a good or permanent joint and the slab is very easily broken at this point especially as prisoners are very destructive and might desire to use the broken pieces for various purposes or get at the plumbing fixtures thus exposed. Constructions according to this invention avoid these serious faults by making the slab which forms the seat integral with the bowl and of such size as to cover the entire niche. Further, prisoners, for any of a number of reasons, throw towels and other material of a similar nature into the toilet with the eif'ect of stopping the closet by becoming wedged in the siphon legs or the trap. I provide the bowl with a small or contracted throat of such size that any material which will pass through the throat will easily pass all the way through the closet.

Other advantages accruing from my improved construction will be apparent from the subjoined description.

The invention consists in the improved construction of water closet hereinafter more particularly described and then specified in the claims. 7

is a vertical section through a water closet constructed in accordance with this invention. Fig. 2 is a plan view of the same.

The entire closet composed of bowl and slab is preferably constructed ofporcelain or other earthy material molded, cast or formed according to the desired type. In the drawings 1 indicates the bowl proper supported by a leg or base 2.

3 indicates a slab of similar material formed integral with the bowl 1 and preferably of such size that it covers or fills the entire niche in which the closet is located. The slab 3 forms the seat for the closet and is provided with a flushing rim 4 sur-' rounding the top of the bowl 1. The slab 3 is provided with a. raised edge or flange 5 on two sides and the back, the front edge of the slab being formed with a swell or bulge 6 in line with the opening in the slab forming the entrance to the bowl 1.

The bowl is provided with the usual siphon discharge 7, 8, the discharge port being indicated at 9. The inlet for the sup ply or flushing water is indicated at 10 and in the construction illustrated these inlet and outlet ports are located at opposite sides of the bowl. The throat 11 forming the entrance to the siphon legs 7 and 8 from the bowl 1 is contracted to form a port or passage much smaller than the size of the passage in the siphon legs by means of a lug or swelling 12 extending into the throat 11 and acting to decrease the normal or usual size of the throat, the object of this feature being, as previously expressed, to insure that anything which passes through the throat will pass entirely through the closet.

13 and 14 indicate two jets both directed toward the siphon leg 7, the jet 13 being located directly beneath the throat 11 and directing the stream of water across the contracted throat 11 and also assisting materially in quickly cleaning the bowl of its contents and keeping any material from clogging the throat.

It will'be understood that the invention is not limited to the exact construction or arrangement as shown except as may be specified in the appended claims.

What I claim as my invention is 1. In a siphon jet water closet, a bowl, a slab integral with the bowl and having an extended fiat surface, raised edges on two sides and the back of the slab and a promediate proximity thereto whereby solid matter lodged in said throat will be directly engaged by the jet of water, the other jet being directed in line with the siphon leg substantially as and for the purpose described.

Signed at Trenton, in the county of Mercer and State of New Jersey, this 1st day of May, A. D. 1915.
